Circuit_04_Potentiometer code example

Example: Circuit_04_Potentiometer

int sensorPin = A0;
int ledPin = 13;  
int sensorValue = 0;

void setup() {
  pinMode(ledPin, OUTPUT);
}

void loop() {
  sensorValue = analogRead(sensorPin);
  sensorValue = map(sensorValue, 0, 1023, 0, 255);
  analogWrite(ledPin, sensorValue);
}
